The company key is not the same as your Business Identification Number (BIN) or your Ontario Corporation Number (OCN). This key acts like a password to secure your business records and authorize transactions in the Ontario Business Registry (OBR) system. Think of it as the PIN for your corporate records, ensuring only authorized individuals can make changes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For new businesses, the Ministry system sends the key to the official email address during registration or incorporation. Existing businesses can <a href=\"https:\/\/www.ontariobusinesscentral.ca\/forms\/company-key.php\">request a company key<\/a> which is e-mailed or mailed to the address on file.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Starting February 1, 2025, the Government of Ontario will require a company key for updates and filings for businesses. This applies to all entities registered in the Ontario Business Registry. Whether you use the OBR self-serve portal, a service provider, or Registry Consultant, the company key will be necessary to access and update your business information.<\/p>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:80.1%\">\n<h2 class=\"wp-block-heading\">Why is a Company Key Important?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The company key is essential for protecting your business from unauthorized changes. Without this safeguard, anyone could potentially alter your business\u2019s records in the public system. With the key, you gain full control and ensure that only authorized parties can access your information. You can give the key to a Service Provider, Registry Consultant, or legal professional to manage business records and transactions.

This includes filings made directly, through intermediaries, or via service providers.<\/li>\n\n\n\n<li><strong>Delegated Authority:<\/strong> Previously, if you didn\u2019t have a company key, you could rely on a Service Provider or Registry Consultant to complete filings for you. Now all businesses must provide their company key to intermediaries or service providers to complete filings on their behalf. This authority remains until explicitly revoked.<\/li>\n\n\n\n<li><strong>Increased Service Provider Options:<\/strong> Businesses will have more choice in selecting service providers, enhancing flexibility and customer experience.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">How Does a Company Key Work?<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The company key functions as an access control mechanism. Here\u2019s how it works:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Obtaining the Key: <\/strong>Automatically issued to new businesses upon registration or incorporation or requested online for existing businesses. You can do this with Ontario Business Central using our<a href=\"https:\/\/www.ontariobusinesscentral.ca\/forms\/company-key.php\"> company key request form<\/a>.<\/li>\n\n\n\n<li><strong>Delegated Authority:<\/strong> To use a Registry Consultant or service provider, you\u2019ll need to share your key with them. Delegated authority remains in place until you revoke it.<\/li>\n\n\n\n<li><strong>Conducting Transactions: <\/strong>Use the key for filing updates, annual returns, and other corporate changes. This can be done through the OBR self-serve portal, a service provider or a Registry Consultant like Ontario Business Central with access to the Ontario Business Registry Partner Portal.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">Ontario Company Key vs Ontario ONe-Key<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">The company key is not the same as an Ontario ONe-Key. A company key is a unique 9-digit code required to link your registered business to your Service Ontario Account. Previously you needed to use ONe-Key for Service Ontario Account access. The ONe-Key system has now been replaced by the My Ontario Account.&nbsp;<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">If you\u2019d like to set up your OBR profile and link your business, you must create or log into an existing My Ontario Account and provide your company key.<\/p>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter\"><a href=\"https:\/\/www.ontariobusinesscentral.ca\/forms\/company-key.php\"><img decoding=\"async\" width=\"1240\" height=\"650\" src=\"https:\/\/www.ontariobusinesscentral.ca\/blog\/wp-content\/uploads\/2022\/09\/company-key.jpg\" alt=\"Protect your business and verify your address with a company key.

This applies to sole proprietorships, corporations, or other entities under the business law statutes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">When you register your business with a Service Provider or Registry Consultant, they automatically have access without needing the key. If you give them the key later, they receive access to complete filings for your business. In both cases, their access stays in place until you revoke it.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Businesses that automatically get a company key in Ontario include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.ontariobusinesscentral.ca\/forms\/business-registration.php\">Business Name Registration<\/a> (Sole Proprietorships &amp; General Partnerships)<\/li>\n\n\n\n<li><a href=\"https:\/\/www.ontariobusinesscentral.ca\/incorporation-online.php\">Articles of Incorporation<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.ontariobusinesscentral.ca\/professional-ontario-incorporation-online.php\">Ontario Professional Corporations<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.ontariobusinesscentral.ca\/forms\/non-profit-incorporation-ontario.php\">Not-for-Profit Corporations<\/a><\/li>\n\n\n\n<li><a href=\"https:\/\/www.ontariobusinesscentral.ca\/forms\/ontario-articles-continuance.php\">Articles of Continuance into Ontario<\/a><\/li>\n\n\n\n<li>Articles of Amalgamation<\/li>\n\n\n\n<li><a href=\"https:\/\/www.ontariobusinesscentral.ca\/blog\/extra-provincial-license-obtained\/\">Extra Provincial Licence<\/a> (Domestic, Foreign &amp; LLC)<\/li>\n\n\n\n<li><a href=\"https:\/\/www.ontariobusinesscentral.ca\/forms\/limited-partnership-business-registration.php\">Limited Partnership<\/a><\/li>\n<\/ul>\n\n\n<figure class=\"wp-block-embed-youtube wp-block-embed is-type-video is-provider-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"lyte-wrapper\" style=\"width:1280px;max-width:100%;margin:5px;\"><div class=\"lyMe\" id=\"WYL_CTykB47i1DM\"><div id=\"lyte_CTykB47i1DM\" data-src=\"\/\/i.ytimg.com\/vi\/CTykB47i1DM\/hqdefault.jpg\" class=\"pL\"><div class=\"tC\"><div class=\"tT\"><\/div><\/div><div class=\"play\"><\/div><div class=\"ctrl\"><div class=\"Lctrl\"><\/div><div class=\"Rctrl\"><\/div><\/div><\/div><noscript><a href=\"https:\/\/youtu.be\/CTykB47i1DM\" rel=\"nofollow noopener\" target=\"_blank\"><img decoding=\"async\" src=\"https:\/\/i.ytimg.com\/vi\/CTykB47i1DM\/0.jpg\" alt=\"YouTube video thumbnail\" width=\"1280\" height=\"700\" \/><br \/>Watch this video on YouTube<\/a><\/noscript><\/div><\/div><div class=\"lL\" style=\"max-width:100%;width:1280px;margin:5px;\"><\/div><figcaption><\/figcaption><\/figure>\n\n\n<h3 class=\"wp-block-heading\">For Existing Businesses<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If your business was registered before October 19, 2021, you need to request a company key.
